Abstract: A trocar assembly (70) formed from a trocar tube subassembly (74) and a separable, interfitting trocar subassembly (72). The trocar tube assembly includes a head (112) having a bore (120) into which a trocar tube (116) is fitted and a manually operated slide valve assembly (118) mounted transversly of the bore in the head. The valve has a bore (134) through it that may be aligned with the bore in the head by movement of the valve. The trocar subassembly includes a head (76) that has a bore (92) extending partly through it in which a trocar obturator (82) and a concentric tubular shield (86) are mounted such that the shield is capable of limited axial movement relative to the obturator between a normal, extended position in which the shield effectively covers the piercing tip (84) of the obturator and a retracted position in which the tip is exposed. The obturator and shield are inserted through the bore in the trocar tube subassembly head, the slide valve bore and the trocar tube. The bore in the slide valve has a radial tooth (136) in it that engages a slot (138) in the shield to reversibly lock the shield in its extended position when the slide valve is in its normal position. The valve is depressed manually to disengage the tooth to allow axial movement of the shield or separation of the trocar subassembly from the trocar tube subassembly.

Abstract: 57 Disclosed is a heterodimeric T lymphocyte receptor comprising an alpha and a beta subunit. Each subunit consists of a signal peptide, variable, joining, constant, transmembrane, and cytoplasmic regions. The two subunits are connected by a disulfide bond between cysteine residues located between the constant and transmembrane region. 
     The structure, amino acid, and nucleotide sequence of the lymphocyte receptor were determined using cDNA clones derived from a functional murine cytotoxic T lymphocyte clone. The genes corresponding to these cDNA are expressed and rearranged specifically in T cells and have significant sequence homologies to immunoglobulin V and C genes. 
     Both the T cell receptor protein and it subunits may be produced from the cDNA clones. The protein molecules may be further used for the production of T-cell clone specific antibodies.

Abstract: The invention relates to pneumatic tyres having a carcase and/or a belt of a rubberised cord fabric, preferably textile fabric, which is composed of sections overlapping at the edges. These overlaps lead to an amassment of the load carriers which can have disadvantageous consequences, e.g. regions of tightness and constrictions during both manufacture and use of the type. In order to eliminate these disadvantages, the cord fibres located in the overlapping region on the basis of the invention have a greater extension than the adjacent cord fibres. This leads to an increased elastic extension which results in the desired compensation. <IMAGE>

Abstract: In an ultrasonic imaging apparatus of the type having a plurality of selectable modes of operation, a motor-driven electroacoustic transducer is steered in a sector field in a predetermined relation to a selected operational mode. The sector scan format of returning echos is converted to a line-by-line raster display format (by scan converter l2) in response to line sync pulses. The number of line sync pulses generated per unit time interval is scaled by a factor of N/M (25, 30), so that it corresponds to the the number of pulses generated by the encoder (2) during the same time interval, where N and M are integers which are variable as a function of the selected mode. Phase comparison (31) is made between the pulses generated by the encoder and the scaled line sync pulses to generate a phase difference signal from which a speed control signal is derived (33) for controlling the speed of the motor. Since phase comparison is made for all the pulses generated by the encoder, the resolution of motor speed control is increased with respect to the number of energy transmissions, eliminating blurred or distorted tomographic images.

Abstract: A method for ion exchange removal of lead ion from solution utilizes a material which is insoluble in the solution and contains ion-exchangeable strontium or calcium or both. Ion exchange removal of even very low concentrations of lead has been found to be selective in the presence of gold and gold-alloying metals such as cobalt, nickel, iron, antimony and indium. The use of strontium or calcium exchange materials is found to be effective to remove lead ion from a liquid in the presence of gold and, e.g., cobalt ion, without significant removal of gold or cobalt. Apparatus in accordance with the invention includes a liquid-permeable contact material comprising an exchange material which may be distended upon a liquid-permeable support for passage therethrough of liquid to be treated. A gold-plating solution in accordance with the invention comprises a source of gold and contains calcium and/or strontium ion and not more than about 20 ppm lead.
